Newly-developed 'graphone' makes spintronic devices closer than ever
19:29 September 3, 2009 PDT
A team of researchers from the Virginia Commonwealth University, Peking University in Beijing, the Chinese Academy of Science, and Tohoku University in Japan has designed a new graphite-based magnetic nanomaterial that behaves as a semiconductor and could prove very important for ongoing research in the field of spintronics.

Sound could be the key in building tomorrow's nanostructures
19:55 September 1, 2009 PDT
Researchers from Penn State University have found a way to precisely manipulate tiny objects using sound rather than optical instruments with a quick, energy-effective and technologically-simple technique that could have important applications in the fields of nanotechnology and biological research.

There have been a few breakthroughs in recent years that hold the promise of sustaining Moore’s Law for some time to come. These include attaching molecules to silicon and replacing copper interconnects with graphene. Now IBM are proposing a new way to pack more power and speed into computer chips by using DNA molecules as scaffolding for transistors fabricated with carbon nanotubes and silicon wires. Read More
Ghostly nano 'kites' may lead to holy grail of nanotube growth

Researchers at Houston’s Rice University have developed a method for making bundles of single-walled carbon nanotubes (SWNT) dubbed “odako”. Eventually, the method may realize meter-long strands of nanotubes that are no wider than a piece of DNA which could be used in lightweight, super-efficient power-transmission lines, in ultra-strong and lightning-resistant materials for airplanes, and may also prove useful in batteries, fuel cells and microelectronics.

Scientists defy gravity with metal that pumps liquid uphill

Gravity can make it difficult to move liquid uphill but scientists at the University of Rochester have created a simple slab of metal that does exactly that using the same wicking process that trees employ to pull vast amounts of water from their roots up to their leaves. The metal could be used to pump microscopic amounts of liquid around a medical diagnostic chip, cool a computer's processor or turn almost any simple metal into an anti-bacterial surface. Read More
